Design of auxiliary parking device of mine-used trackless rubber-tyred vehicle

In view of hidden security trouble in astern running for trackless rubber-tyred vehicle, an auxiliary parking device of mine-used trackless rubber-tyred vehicle was designed, and acquisition principle of signals of astern running distance, image, running direction of the vehicle and input signal of switchover of the device were introduced. The practical application result shows that the device has stable and reliable performance, and can effectively monitor 400-2 000 mm astern running distance and clearly display video image of astern running under low illumination environment, which solves security problem of astern running in unsighted area.
